Speed in general is given by 
We know that the wave is travelling with a speed of light in vaccum therefore
Wave speed is given by:-
Here T is time period of the wave
or
Here f is frequency of the wave
Hence
Option -1 and Option - 4 are correct answer.

The relations between wavelength, frequency, period, and speed of propagation apply to all wave phenomena, not just electromagnetic radiation. The C key on a piano has a fundamental frequency of about 256 Hz. What is the corresponding wavelength of the sound waves? (The speed of sound in air varies with temperature but is about 340 m/s at room temperature.)
